Vicki PfauandGreg Kroah-Hartman cbc82e7db1 Input: xpad - fix Share button on Xbox One controllers 
commit 4ef4636707 upstream.

The Share button, if present, is always one of two offsets from the end of the
file, depending on the presence of a specific interface. As we lack parsing for
the identify packet we can't automatically determine the presence of that
interface, but we can hardcode which of these offsets is correct for a given
controller.

More controllers are probably fixable by adding the MAP_SHARE_BUTTON in the
future, but for now I only added the ones that I have the ability to test
directly.

commit 11cdb506d0 upstream.

In mtk_pmic_keys_probe, the regs parameter is only set if the button is
parsed in the device tree. However, on hardware where the button is left
floating, that node will most likely be removed not to enable that
input. In that case the code will try to dereference a null pointer.

Let's use the regs struct instead as it is defined for all supported
platforms. Note that it is ok setting the key reg even if that latter is
disabled as the interrupt won't be enabled anyway.

commit 7675b5efd8 upstream.

The power control function ignores the "on" argument when setting the

Fix by sending the state variable, which contains the proper HID_POWER_ON or
HID_POWER_SLEEP based on the "on" argument.

Jeff LaBundyandGreg Kroah-Hartman 0b5b6512f6 Input: iqs7222 - preserve system status register 
commit a2add51331 upstream.

Some register groups reserve a byte at the end of their continuous
address space. Depending on the variant of silicon, this field may
share the same memory space as the lower byte of the system status
register (0x10).

In these cases, caching the reserved byte and writing it later may
effectively reset the device depending on what happened in between
the read and write operations.

Solve this problem by avoiding any access to this last byte within
offending register groups. This method replaces a workaround which
attempted to write the reserved byte with up-to-date contents, but
left a small window in which updates by the device could have been
clobbered.

Now that the driver does not touch these reserved bytes, the order
in which the device's registers are written no longer matters, and
they can be written in their natural order. The new method is also
much more generic, and can be more easily extended to new variants
of silicon with different register maps.

As part of this change, the register read and write functions must
be gently updated to support byte access instead of word access.

Dmitry TorokhovandGreg Kroah-Hartman a2cbcd7013 Input: synaptics - fix crash when enabling pass-through port 
[ Upstream commit 08bd5b7c9a ]

When enabling a pass-through port an interrupt might come before psmouse
driver binds to the pass-through port. However synaptics sub-driver
tries to access psmouse instance presumably associated with the
pass-through port to figure out if only 1 byte of response or entire
protocol packet needs to be forwarded to the pass-through port and may
crash if psmouse instance has not been attached to the port yet.

Fix the crash by introducing open() and close() methods for the port and
check if the port is open before trying to access psmouse instance.
Because psmouse calls serio_open() only after attaching psmouse instance
to serio port instance this prevents the potential crash.

Mark PearsonandGreg Kroah-Hartman dc8c9c171e Input: atkbd - map F23 key to support default copilot shortcut 
commit 907bc9268a upstream.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
dedicated keycode, and multiple vendors have their keyboards emit this
sequence in response to users pressing a dedicated "Copilot" key.
Unfortunately the default keymap table in atkbd does not map scancode
0x6e (F23) and so the key combination does not work even if userspace
is ready to handle it.

Because this behavior is common between multiple vendors and the
scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
key sequence is generated properly.

MS documentation for the scan code:
https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
Confirmed on Lenovo, HP and Dell machines by Canonical.
Tested on Lenovo T14s G6 AMD.

Dmitry TorokhovandGreg Kroah-Hartman ceec8ad091 Input: edt-ft5x06 - fix regmap leak when probe fails 
[ Upstream commit bffdf9d7e5 ]

The driver neglects to free the instance of I2C regmap constructed at
the beginning of the edt_ft5x06_ts_probe() method when probe fails.
Additionally edt_ft5x06_ts_remove() is freeing the regmap too early,
before the rest of the device resources that are managed by devm are
released.

Fix this by installing a custom devm action that will ensure that the
regmap is released at the right time during normal teardown as well as
in case of probe failure.

Note that devm_regmap_init_i2c() could not be used because the driver
may replace the original regmap with a regmap specific for M06 devices
in the middle of the probe, and using devm_regmap_init_i2c() would
result in releasing the M06 regmap too early.

Mathias KrauseandGreg Kroah-Hartman 1881193bf2 Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removal 
commit fbf8d71742 upstream.

Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.

With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.

Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

[ Upstream commit 206f533a0a ]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

When exercising uinput interface syzkaller may try setting up device
with a really large number of slots, which causes memory allocation
failure in input_mt_init_slots(). While this allocation failure is
handled properly and request is rejected, it results in syzkaller
reports. Additionally, such request may put undue burden on the
system which will try to free a lot of memory for a bogus request.

Fix it by limiting allowed number of slots to 100. This can easily
be extended if we see devices that can track more than 100 contacts.
